Molar massive is the mass of one mole the a compound. One mole is 6.02x10^23 molecule of that compound.

The formula for magnesium oxide is MgO. This means every molecule the magnesium oxide includes one magnesium atom and also one oxygen atom. In bespeak to find the molar mass of a compound, you must sum the separation, personal, instance molar masses that the atom which kind that compound.

The molar massive of an element is the atomic weight of that element. Making use of the table girlfriend provided, we find the molar masses the Mg and also O are 24.305 grams/mol and 15.999 grams/mol, respectively.

So the molar fixed of magnesium oxide is (24.305 + 15.999) = 40.304 grams/mole.
